The phrase “Multicultural symbiosis” came to be used around 1990 owing to the increasing number of foreign workers in Japan. In this thesis, I focused on Mie Prefecture and examined the actual situation of foreign residents and what measures were taken for them. The reason why I focused on Mie Prefecture is that it has the third largest percentage of foreign residents(2.3%) in Japan. In Mie Prefecture, there are some governmental and nongovernmental measures for foreign residents.I especially focused on children who have international backgrounds: specifically, a child of mixed parentage and a Japanese-Brazilian. I visited Sasagawa housing complex in Mie Prefecture to understand the actual situation there. I made a study by doing observation of children who live in this housing complex. I investigated children at “Sasagawa Children Class”, a free study support class. Most of the children who go to this class are not good at Japanese. It is managed by “Multicultural Symbiosis Center” in Sasagawa housing complex.I found that there are a lot of children who are confronted with ploblems of language and they feel worried about their own identity. In this thesis, I analyzed children’s expression. For instance, there were also children who had a negative feeling about their mothers’ language because they are not able to communicate with their mothers easily. However, I consider that there are fewer children who are worried about their own identity than in other areas of Japan because children who are non-Japanese are not the minority in Sasagawa housing complex.
